Our Nurse Practitioners and Physician Assistant Team

In addition to our physicians, NY Family Docs has an outstanding team of Nurse Practitioners (NP) and Physician Assistants (PA) that care for our patients, providing a full range of services. All of them are bilingual, speaking both English and Spanish.

A Nurse Practitioner, is an advanced practice registered nurse who is trained to assess patient needs, order and interpret diagnostic and laboratory tests, diagnose disease, formulate and prescribe treatment plans. Their NP training is done after their completion of nursing school and often after several years of nursing practice.

A Physician Assistant (PA) is a medical provider who diagnoses illness, develops and manages treatment plans, prescribes medications, and often serves as a patient’s principal healthcare professional. With thousands of hours of medical training, completed after finishing college, PAs are versatile and collaborative. PAs practice in every state and in every medical setting and specialty, improving healthcare access and quality.
